Interior home design in the 1970s leaned towards vibrant colors, loud patterns and the always-present wall paneling. Those who have lived during that era know that wall paneling meant dark, knotty pine (or faux wood) that absorbs all the light inside the room and gives it a cramped, airless feel. The thought of adding wall paneling inside the home can still make some homeowners cringe – but maybe not once they know that this design trend has already come a long way.
